its max 15
weapon crit* weapon aps < 15
asume you have 4active trigger gems you wana CoC, 4gems*6.66/0.5crit chance = 53hits per second
well, vs multiple targets you do 666hits per second, so thats not the problem
vs single target, with Rain of arrows, unlinked, you may do 13hits per attack vs single target
53/13 = 4aps
https://pathofexile.gamepedia.com/Windripper9crit chance * 1.67aps = 15.03
4aps needed / 1.67 -1)*100 = 140%increased attack speed needed
50crit chance / 9crit chance-1)*100 = 455%increased crit chance needed
if you have that, you can go upto 27spells casts per min
27/4= only 6.75active gems linked to cwdt would result in the same disco
if link 14gems to cwdt, you have same dps, if you have 50%lvled-up cwdt, witch require 4500heal per second
4500 heal per sec same disco as 455%crit chance and 140%attack speed (more then 44passive notes)
